火焰原子吸收光谱法分析沉积物中重金属元素的形态

Analysis of speciation of heavy metal elements in Jinshajiang river sediments by flame atomic absorption spectrometry

采用原子吸收光谱法研究了金沙江攀枝花段水系沉积物中重金属的形态及分布特征。研究发现,各重金属的形态以残渣态为主,离子交换态含量很少。同时说明原子吸收光谱法完全可以用来研究重金属形态特征,在环境研究中具有重要意义。

In this paper, the speciation characteristics of heavy metals in Jinshajiang （Panzhihua） sediments by using continuous extraction and AAS. The results show that the most speciation is residua and the least speciation is ion exchange. Meanwhile, the results also indicate that AAS is a good method for analyzing the speciation of heavy metals.
